Is it possible to include a % surcharge fee?

Hey everyone, is it possible create a service-based product that has multiple line items associated with it. My use case is that I want to charge customers for a particular service and then charge a % fee surcharge on top of whatever the service fee is.

So it would be something like:
Service: $100
Surcharge (5%): $5
Subtotal: $105

Taxes: $10
Discount: $0
Total: $115

Is anything like that possible?
